. BELT-.SPLITTING DEVICE.-

Application filed November 22, 1917, Serial No. 203,383. 'ItenewedFebruary 26, 1919. Serial No. 279,4.1'7.

a simple and efi'ective device for longitudinally splitting, or trimminga belt or strip of flexible material passed therethrough and isespecially designed for splitting strips of leather belts into strips,although its function is not thereby limited to such use.

More specifically the invention embodles mechanism by the use of which acontinuous or substantially continuous strip of material, such as aleather belt may be split, divided or trimmed longitudinally into aplurality of separate strips, easily and economlcally and by the use ofwhich the edges or sides of the severed or split away sections of theoriginal article are parallel with one of the sides of the originalstrip.

Furthermore the invention contemplates the provision of a simple machineby which a strip of material may be divided, spl t or trimmed; saidmachine embodying adJustable means for controlling the transverse widthof the portions, cut, severed or vided from the original or initlalstrip, said means comprising a cutting or trimming tool in associationwith a guide for the strip of material, and means to shift the positionof said guide with respect to said cutting tool whereby the widths ofthe severed sections may be easily predetermined.

With the foregoing and other objects in view, the invention consists inthe novel construction, combination and arrangement of parts,constituting the invention to be hereinafter specifically described andillustrated in the accompanyingdrawings, whlch form a part hereof,wherein is shown the preferred embodiment of the invention, but it is tobe understood that changes, variations and modifications, may beresorted to which come within the scope of the matter hereinafterclaimed.-

Figure l, is a perspective view of the machine embodying the presentinvention.

Fig. 2, is a plan, view of the device, shown in Fig. 1.

Fig. 3 is a sectional View taken approximately on line 3 of Fig. 2.'

Referring to the drawings in detail, the device embodies a framecomprising side members, 1 and 2, arranged in parallelism and connectedat their ends by end-bars 3 and 4. The members 1& are all preferablyformed integrally and depending from the member 1 is a bracket 5,provided with openings 6 through which may be passed holding memberssuch as bolts for securing the device to some fixed instrumentality,such Specification of Letters Patent.

ill

for instance as a bench. Extending; up-

wardly from the end member 4; is a support 7 provided with a bifurcatedupper end and extending upwardly and preferably formed integrally withthe end member 3 is a sup port 8, similar to the support 7 and providedwith a bifurcated end. Secured in the slots formed by the bifurcationsin the supports 7 and 8 is a guide rod 9 provided with graduations 10.The guide rod 9 is secured at its ends in the supports 7 and 8 by meansof holding members such for instance as pins 11.

Positioned immediately below the openingin the upright 8-, in the endmember 3 1s a socket 12, constituting a bearing, and in the member 4: isa bearlng 13 whch is in exact alinement with bearing 12 and in verticalalinement with the guide bar 9. The bearings 12 and 13 constitutesupporting means for a threaded shaft 14 which is mounted therein, oneend of which is formed to seat in the bearing 12, and with the 0p positeend cylindrically fastened to be seated in the opening in the bearing13. The intermediate portion of the shaft 1a is provided with screwthreads 15 for a purpose to be later described. The shaft 14 is heldfrom longitudinal movement by means of a collar 16, mounted on the shaft14: adjacent to the bearing 13 and this collar 16 is held in place bymeans of a cotter pin 17. Outside of the end member 4 the shaft" 14: isprovided with an operating head 18, preferably provided with a knurlededge.

Mounted on the threaded portion of the shaft 14.- is a guide 19preferably in the form of a cylindrical wheel, one portion of which hasa radial slot 20 which receives the guide bar 9 and is provided with acentral opening which is interiorly threaded to receive the shaft 14, sothat When the male threads of the shaft 14 are rotated through themedium of the head 18-, the guide 19 is shifted longitudinally of theshaft 14, due to the engagement of the female threads in the member 19.The guide 19 is of such diameter as to partially inclose the guide bar9, and the side faces of said guide 19 indicate on the guide bar 9 thedesired position of the guide 19 on the guide bar 9.

The side bar or member 2 is provided with an outwardly projecting lug21, provided with an aperture in which is mounted a cap screw 22.Secured by means of the cap screw 22 to the inner face of the side bar 2is a tool holder 23-, comprising a base 2 1 and a pair of outwardly andhorizontally projecting converging arms 25, the outer ends of which areprovided with alined open ings to receive a clamping bolt 26. Arrangedto be held in position by the tool holder 23 is a cutting tool 27, whichis provided with an opening through which passes the clamping bolt 26,and which is secured in position thereby. The cutting tool 27 isarranged to extend from the guide bar. 9 downwardly below the shaft 14:.In order to steady the upper end of the cutting tool 27 there isprovided a notched lug 28, on the appropriate face of the guide bar 9,and so positioned that the edge of the cutting tool 27 and the guide 19may be varied by rotating the shaft 14; through the medium of the head18, and hence a strip 30 of any desired width may be produced from theinitial strip 29.

I claim.

A device of the class designated embody ing a frame comprising side andend members, a guide bar mounted on said'end membore, a lug on saidguide bar provided with a notch extending transversely to-said bar, athreaded shaft mounted in said end members, a guide shiftably mounted onsaid threaded shaft and provided with a slot to receive said guide bar,a tool-support connected with one side member of said frame, and acutting tool mounted in said support and disposed at an angle to saidguide bar,-

and with a portion thereof engaging in the notch in the lug'on saidguide bar for holding said cutting tool against lateral movement. 9

In testimony whereof I have hereunto set my hand.
